Its function is to proxy network users to obtain network information. Image said: it is the network information relay station. Under normal circumstances, when we use a web browser to connect directly to other Internet sites to obtain network information, we directly contact the destination site server, and then the destination site server transmits the information back. A proxy server is another server between the browser and the Web server. With it, the browser does not go directly to the Web server to retrieve the Web page but sends a request to the proxy server. The signal will be sent to the proxy server first, and the proxy server will retrieve the information needed by the browser and send it to your browser.
